Abstract

Méthode pour vérifier un affichage effectif d’un message d’intérêt sur un afficheur digital (1), la méthode comprenant : disposer un capteur optique (2) en regard de la face d’affichage de l’afficheur digital ; préparer et afficher une trame d’affichage (20) du message comprenant une succession séquencée d’images passives et d’images actives ; la trame étant associée à un code numérique de signature ; les images actives étant définies par rapport à au moins une image significative de message (A, B, C) ; les images passives ou les images actives comprenant en outre une image d’affichage du message d’intérêt (F) ; acquérir le signal délivré par le capteur optique (2), et en former un code reçu (21) ; comparer le code reçu (21) avec le code numérique de signature. Figure de l’abrégé : 4A method for verifying effective display of a message of interest on a digital display (1), the method comprising: disposing an optical sensor (2) facing the display face of the digital display; preparing and displaying a display frame (20) of the message comprising a sequenced succession of passive images and active images; the frame being associated with a digital signature code; the active images being defined with respect to at least one significant message image (A, B, C); passive images or active images further comprising a display image of the message of interest (F); acquiring the signal delivered by the optical sensor (2), and forming a received code (21) therefrom; comparing the received code (21) with the digital signature code.
